The SMAJ17A-ES/61 is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Vishay. It is designed to protect sensitive electronic components from voltage transients induced by inductive load switching, lightning, and electrostatic discharge (ESD). The device comes in an SMA package, making it suitable for automated placement in high-density applications. This TVS diode features a glass-passivated junction for enhanced reliability and performance under harsh conditions. The SMAJ17A-ES/61 is a unidirectional TVS, meaning it provides protection against positive voltage transients.
